California Transparency in Supply Chain Act(SB 657)

​The California Transparency in Supply Chain Act (SB 657) requires retail sellers and manufacturers doing business in California to disclose their efforts to eradicate slavery and human trafficking from their direct supply chain.

The vast majority of the products Omya sells are processed with stone that we quarry locally from our own facilities or are purchased from vendors located in the United States.

Omya Inc. strives to conduct business in a sustainable manner including economic growth, ecological balance and social progress. Our efforts toward sustainable development are discussed in our Corporate Sustainability Policy.

Upon hire, all new Omya Inc. employees receive a personal letter from our Global CEO setting the expectation that our employees should comply with our corporate policies to respect people, the environment, and all national and international laws. Finally, as part of our standard terms and conditions, we require our suppliers to comply with applicable laws and regulations.

Our policies and values define the foundation upon which Omya Inc. conducts its business. Omya Inc. will never use forced labor in any of our operations and we will not conduct business with any third party that is known to engage in such practices. Any concerns regarding human trafficking and slavery in our supply chain will be promptly investigated; validated concerns will result in immediate action.
